Comparison of Various Prosthetic Foot-Ankle Mechanisms

Enrolling by invitation · Not applicable

Conditions studied: Transtibial Amputation - Unilateral

In brief

In summary, subjects will be asked to wear a number of sensors and use different ankle-foot prostheses in place of their customary prosthesis. Data will be collected from the wearable sensors, VICON motion capture system, video cameras, and force sensors in the ground as they walk on level-ground, on a treadmill, and on stairs. The controller of any powered prosthesis will be electronically adjusted between trials or while the subject walks to determine how their gait changes in response to these changes. Trials will also be conducted with a standard passive prosthesis that would be prescribed for a person of similar height and weight.
